There is speculation that the Cowboys, who are facing a tight salary cap position, might instead re-sign Dez Bryant to a long-term deal and target Adrian Peterson for less than it would cost to re-sign Murray. This is despite the fact Murray rushed for a franchise-record 1,845 yards this season.

Coach Jason Garrett recently called Murray the Cowboys' "identity," which means things will become very interesting in Dallas when the NFL free-agenct market opens on March 10.

"Those are guys that I've spent my entire career with, those are guys that I've become great friends with," Murray said Thursday in an interview with Dallas radio station KRLD. "I consider them my brothers, and I love playing with those guys, you never know what's going to happen, we'll see what happens. But all you can do is hope for the best."
